usbfs disappears on recent kernels [1], at least for desktop machines
(and most certainly on my stock distribution). Don't want to be contra
productive here, but if you insist on this "proof" (i.e. don't accept
the output of the above lsusb command or my forum discussion reference
[2] as proof enough) and want me to spend another hour compiling a
kernel with enabled usbfs for such a small fix, then I'll pass on this
one for now.
just run the attached script. It does the same thing. Or you could just
mount usbfs.
There is *no* usbfs available in my current kernel - I'd need to enable
and recompile: that's why I can't mount. Distribution vendors (like
Ubuntu) follow the recommendation concerning usbfs support in their
stock kernels (it's marked deprecated).
Your script does not work on devices attached to (internal) hubs - they
are silently omitted. I modified it accordingly and that's the output:

I: If#=03 Alt=0 #EPs=00 Cls=fe(apspe) Sub=01 Prot=01 Driver=(none)
As visible here and in my previously quoted lsusb output the class isn't
set correctly (0xff instead of 0xe0), so the driver won't detect the
device. It does here, because - of course - I run the patched btusb module.
When I remove my patched DKMS module (and use the stock module as
shipped in 2.6.32), the output is:
T: Bus=1 Dev#=8 Spd=12 MxCh=0
D: Ver=2.00 Cls=ff(vendr) Sub=01 Prot=01 MxPS=64 #Cfgs=1

I hope you're finally convinced, so attached once more the patch (and CC
to linux-bluetooth).
